1. Push the Turbine/Motor Selector Switch, and the green lamp will light up and the air
turbine will be selected.
2. • When the auto cruise mechanism is OFF :
Depress the Knee Controller or the Pedal, and the turbine will rotate.
• When the auto cruise mechanism is ON:
Push the Auto Cruise Switch and depress the Knee Controller or the Pedal, and
after a lapse of two seconds, the turbine will continue rotating even if the Knee
Controller or the Pedal is released.
3. To cancel the auto cruise mechanism, depress the Knee Controller or the Pedal again
or push the Auto Cruise Switch.
Even if Forward/Reverse Selector Switch is pushed while using the air turbine, it will be
neglected only with the beeps of electronic sounds.
4. Push the Turbine/Motor Select Switch again, and the lamp will go out and the motor will
be available.

For the use of a small-diameter round bur or
fisher bur at 40,000min
-1
(rpm) or more, pressing
the Speed Limit Release Button, which is
equipped with the Speed Control Knob, and
turning the speed control knob allows a setting
of up to 50,000min
-1
(rpm). (Fig.7)

5. Operation Procedure of Air Turbine
(Option)
When the motor is operated with a load exceeding the limit or the handpiece is in an
unrotatable condition, the circuit to protect the motor and unit operates to stop the power
supply to the motor, whereby an error code appears on the Indicator.
How to reset the protective circuit
It can be reset by depressing the Knee Controller or Pedal again after eliminating the
cause of the error.
6. Protective Circuit
When the Power Switch is turned on, the rotation direction made when the switch was last
turned off are restored. Special attention should be given to the rotation direction.
7. Memory Function
When the motor is stopped due to some trouble such as a failure, overload, wire breakage or
misuse, Speed Display displays the error code for checking the status of the unit and
understanding the cause of the trouble easily.
8. Error Code
Fig. 7
CAUTION
Use of 40,000min
-1
(rpm) or more is allowable only when the bur manufacturer or dealer
specifies that the bur's acceptable rotation speed is 40,000min
-1
(rpm) or more. If the
use of more than the acceptable rotation speed is made, the bur may be broken.

Cause
• Abnormal internal memory
• Broken internal memory
• Long-time use at a high load (overcorrect)
• Shorted cord (power line)
• Shorted motor winding
• Failure of a turbine adapter
• Shorted cord (power line), damaged circuit
• Broken internal circuit
• Failure of a turbine adapter
• Faulty sensor (Hall IC) in the motor
• Disconnected motor cord
• Severed cord (signal line)
• Open chuck
• Faulty handpiece
• If the cord of the turbine adapter is loosed.
• Temperature rise in the unit due to longtime
use at a high load
• Unit placed under high temperature
• Abnormal voltage generated in start / stop
circuit
• Faulty start / stop circuit from PAM (L Slide)
• Open chuck
• Faulty handpiece
• Motor Faulty
• Faulty sensor (Hall IC) in the motor
• Severed cord (signal, power line)
• Long-time use at a high load (overcorrect)
• Shorted cord (power line)
• Shortstop of the motor winding
• Failure of a turbine adapter
Faulty motor and circuit
• Faulty Foot Pedal or Shorted Foot Pedal cord
• Broken internal circuit
